ALPHONSE DAVID WEIL, OF PARIS, FRANCE.

SYSTEM OF ROUNDABOUTS.

SPECIFICATION forming part of Letters Patent N 0. 663,948, dated December 18, 1900- Application filed March 21,1900. Serial No- 9,566- (No model.)

To all whom it may concern:

Be it known that I, ALPHONSE DAVID WEIL, merchant, of 10. Rue Saints-Cecile, in the city of Paris, Republic of France, have invented a System of Roundabouts, of which the following is a full, clear, and exact description.

This invention relates to a new system of roundabouts in which the horses receive circular motion in varying respective speeds, so as to afford the illusion of a race.

My invention includes an undulated movable track by which the arms attached to the vertical stems of each horse place themselves alternately in contact with movable toothed circles, which receive, respectively, difierent speeds and act as drivers.

The invention is shown in the accompanying drawings, in which Figure 1 is a cross-section of the whole of my device in an arrangement for three horses. Fig. 2 showsin cross-section the mechanism for one of each of the horses. Fig. 3 is a side View of the same. Fig. 4 shows one of the undulated movable tracks which serve to lift and lower the arms attached to the vertical stem of each horse. Fig. 5 is a detail view.

In the several figures the same letters of ref erence indicate like parts.

As shown in the drawings, my device comprises a circular frame a, provided with brackets 1), upon which the rails c are secured. Said rails 0 receive the rollers cl of the carriage d, in which is inserted a vertical rod or stem e, which carries the horsef. The lowercontinuation of the vertical stem is provided with a helical spring g and a socket h, terminated by a fork 2, provided with a roller j. The roller j moves upon a movable track 7c, provided with undulations, which act as cams for lifting the socket h of the stem e, while the helical spring g, acting downward on the socket, causes the roller j to go down into the recesses of the track. The undulated track 7c is provided with an indented rack Z, gearing with a pinion m, carried by the driving-shaft n, to which motion is transmitted by the motor 0, preferably located in the middle of the roundabout, Fig. 1. r The driving-shaft 11. carries a pinion p, gearing with a gear-wheel q, having on its front two toothed Wheels r s, which transmit motion to two parallel horizontal toothed circles u t or drivers, whose centers are the same as that of the roundabout. When the shaft '12 is put in motion, it drives the undulated track 70 by the action of the pinion m on the indented rack l. The said driving of the track 70 will lift roller j, and in consequence also the socket h, and place the upper arm n of the said socket in contact with the horizontal toothed circle or driver a. The horse thus receives the motion of the circle M, which itself derives motion through the wheel (1 and the pinion p,carried by the driving-shaft When the roller j comes down into a recess of the track it, it is followed down by the socket it, acted upon by the spring g. Thus the arm n of the socket disengages itself from the circle u, and thearm w of the socket is placed in contact with the circle or driver if. The horse will then receive its motion from and take the speed of the circle t.

I can arrange any number of horses side by side.

The forms, details, and accessories of my device may of course vary without departing in any way from the principle of my invention.

I claim 1. In combination in a roundabout, an undulating movable track 7c, means for driving the same, a plurality of drivers moving at different speeds, the figure to which motion is to be imparted, and means controlled by the undulating track to throw the said figure into connection with first one driver and then the other, substantially as described.

2. In combination in a roundabout, a movableu ndulating track 7s, a rack thereon, a pinion m, meshing with said rack, thefigure to be driven, a socket it connected therewith and having an arm o, a plurality of drivers 13, u, a gear-wheel g having means for giving the said drivers a differential speed, a pinion p for moving the gear-wheel q, a drive-shaft n, carrying the pinions m and p, the carriage or slide cl for guiding the horse, the rails upon which the slide moves, and a connection be tween the figure and the socket, substantially as described.

The foregoing specification of my system of roundabouts signed by me this 8th day of March, 1900.

ALPHONSE DAVID WEIL.
